Résumé
Extreme weather events are likely to increase in the future, and thus damage to the environment and infrastructure will likely increase during this time, too. To adapt to these weather impacts, forecasting, now-casting, and in situ monitoring installations have increased during the last years. Even though monitoring stations deliver frequent measurements in realtime, a dynamic implementation of measurement frequencies, adapted to certain environmental conditions, are rarely implemented. Within this paper we provide a framework where low frequency phosphorus measurements in the Mondsee catchment can be adapted to high frequency measurements during storm events. When heavy rainfall is observed, a threshold event triggers a reconfiguration task for the phosphorus measurement device, using asynchronous, push-based communication. A Sensor Planning Service commits such a request into the wireless sensor network, and updates the measurement frequency of the target nodes to enable nutrient peak flow estimation during storm events. This setup introduces the possibility of measurements in flooded areas without using traditional (manual) sampling methods, and we expect to obtain a better understanding of discharge to phosphorus runoff relations.
